Hi, i have following problem. At work we have HP proliant ml350 server with windows server 2008 on it, 3x windows 7 client and 25x win xp sp2 clients. Network doesn't work, clients cant see each other, can't see server and server can't see them in network and sharing center. What could be a problem? Is ipv6 protokol on windows 7 opstructing a server or something else?
